Communication
Zoom Phone
Zoom Phone is a cloud-based business phone system offering calling, voicemail, and call management fully integrated with the Zoom platform.
What is Zoom Phone?
Zoom Phone launched in 2019 as Zoom's expansion beyond video meetings into full cloud telephony — a strategic move to capture the business phone system market that traditional PBX vendors and early UCaaS providers had been serving for decades. Built on the same client infrastructure as Zoom Meetings, Zoom Phone lets organizations replace their legacy phone systems with cloud-based PSTN calling, voicemail, call recording, auto-attendants, and call queues, all managed through the familiar Zoom admin console. By 2023, Zoom Phone had grown to over 5 million paid seats, making it one of the fastest-adopted business phone platforms in the UCaaS market.
The architecture leverages Zoom's globally distributed cloud infrastructure, with telephony services running alongside video meeting capacity on the same underlying platform. PSTN connectivity is provided through Zoom's own carrier relationships or through customer-provided SIP trunks (Bring Your Own Carrier). The Zoom desktop and mobile apps handle both video and phone calls under a unified interface — making the transition from a video meeting to a PSTN call and back seamless. Call routing rules, IVR configurations, and auto-attendant trees are managed through the Zoom admin portal and propagated in real time to the distributed infrastructure.
When Zoom Phone experiences a service disruption, businesses face a communication failure that's difficult to route around because the platform serves as the primary phone number. Inbound PSTN calls fail to reach employees, with callers receiving busy signals or going directly to voicemail that may also be inaccessible. Outbound calls cannot dial out. Call queue routing breaks, meaning customers expecting to reach a specific department are either disconnected or receive no answer. Auto-attendant IVR trees stop functioning, replacing a professional call routing experience with a broken greeting. Voicemail retrieval and call recording access may become unavailable simultaneously with the calling disruption.
